Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe mammal declines in Everglades National Park have been linked to Burmese pythons.
What are the characteristics of pythons?Python is a genus of constricting snakes in the Pythonidae family native to the tropics and subtropics of the Eastern Hemisphere. The name Python was proposed by François Marie Daudin in 1803 for non-venomous flecked snakes.
According to the pressure reading, the snake generated almost 300 millimeters of mercury or just under 6 pounds of pressure per square inch (psi) during constriction. “There's a myth that they squeeze their prey until they can't breathe anymore, but that's not accurate.
Pythons can't move very fast though—only about 1 mile per hour (1.6 kilometers per hour) on open ground. But since they don't have to chase their food, they don't really need to move quickly.

What type of mutation is point?
Answer on the explanation part
A point metamorphosis is a type of metamorphosis in Gene or Deoxyribonucleic acid, the cell’s hereditary material, at which point an individual distinct nucleotide base is added, removed, or changed. Chromosomes and Deoxyribonucleic acid are containing many nucleotides. Five various fragments can reconcile nitrogenous bases on nucleotides: cytosine, guanine, adenine, thymine (in DNA), and uracil (in Deoxyribonucleic acid), shortened C, G, A, T, and U. The distinguishing order of nucleotides encodes all the facts for completing activity all cell processes. Usually, a metamorphosis is when a deoxyribonucleic acid is changed through a change in Deoxyribonucleic acid makeup; this may apply even to complete portions of chromosomes. A point metamorphosis is particularly when alone nucleotide base is changed by some means, even though diversified point mutations can happen in an individual string of DNA or Deoxyribonucleic acid.read more on point mutation

Which of the following is TRUE for the RNA polymerase activity? Explanation: RNA polymerase is also known as DNA dependent RNA polymerase enzyme and it involves a synthesis of RNA from DNA.
RNA polymerase, also referred to as DNA dependent RNA polymerase enzyme, produces RNA from DNA.
Ribosomal RNAs (rRNAs) are produced by RNA polymerase I, mRNAs and short regulatory RNAs are produced by RNA polymerase II, and transfer RNAs are produced by RNA polymerase III (tRNAs). DNA viruses use DNA-dependent DNA polymerases (also known as DNA polymerases) to replicate their genomes and DNA-dependent RNA polymerases to transcribe mRNA (also called RNA polymerases). The RNA polymerase is slower, less effective, and less accurate than the DNA polymerase, according to this definition.

the portions of the nervous system outside the central nervous system.
The peripheral nervous system (PNS) is the portion of the nervous system that exists outside of the central nervous system (CNS). It is composed of all the nerves and ganglia that connect the CNS to the rest of the body.
This system is responsible for sending sensory information to the CNS, such as pain, temperature, and pressure, and for sending motor commands from the CNS to the muscles and glands.
The PNS is also involved in controlling reflexes, which are involuntary reactions to stimuli. It is divided into the somatic nervous system, which is responsible for voluntary control of skeletal muscles, and the autonomic nervous system, which is responsible for involuntary control of organs and glands.
The sympathetic nervous system and the parasympathetic nervous system are subsets of the autonomic nervous system. The enteric nervous system, which controls the digestive system, is also a part of the PNS.

Explain the link between dna sequence and protein structure and function.
The sequence of the DNA directly determines the structure and function of the protein it codes for. The DNA sequence gets transcribed into RNA and then further translated to give a protein product.
Transcription is the process of making an RNA copy from a particular gene's DNA sequence. This copy is known as the messenger RNA or the mRNA. The mRNA carries the gene's protein information which is encoded in DNA.
The mRNA thus formed undergoes translation in order to form the respective protein and hence the sequence of the DNA directly influences the structure as well as function of the protein. If there is any mutation in the sequence of the DNA, it also alters both the structure as well as function of the protein product formed.

An electron occupies the lowest energy orbital that can receive it *
The lowest energy orbital that can receive an electron is the ground state orbital, which is the lowest energy state an electron can occupy.
This occurs when the electron is in its most stable configuration, meaning that it has the lowest possible energy and is in the lowest possible energy level. To reach the ground state, the electron must release any potential energy it has and move to the lowest energy level. In an atom, this is the closest orbital to the nucleus.
The ground state orbital is also known as the "fundamental state" because it is the most basic and fundamental state of an electron. The properties of the ground state orbital depend on the atom in question and its size. In general, the ground state orbital is the closest orbital to the nucleus and has the lowest energy level of the atom.

The production of fsh by the anterior pituitary is reduced by which hormone?
The production of FSH (follicle-stimulating hormone) by the anterior pituitary is reduced by the hormone inhibin.
Inhibin is produced by the granulosa cells of the ovary in females and the Sertoli cells of the testes in males. It travels to the anterior pituitary and signals to reduce the production and release of FSH. This helps to regulate the balance of hormones in the body and prevent overstimulation of the ovaries or testes. Inhibin also plays a role in the regulation of the menstrual cycle in females, helping to prevent overstimulation of the ovaries and the formation of multiple follicles.
A protein called inhibin is secreted by the granulosa cells in women and the Sertoli cells in men. It decreases the amount of LH-releasing hormone in the hypothalamus and prevents the pituitary gland from producing and releasing follicle-stimulating hormone.

the water potential for cell AND the solution in the beaker. Explain in which direction will the net water flow
and include a diagram to support your explanation.
In a beaker containing 0.50 M sucrose, a cell is inserted with a Y of -7.0 bars and a V of -3.0 bars. One of the elements of water potential is the solute potential, also referred to as osmotic potential.
How do you know which direction the net flow of water will be?The equation s = -iCRT can be used to compute the potential of the solute. While there are solutes in solution, the solute potential always has a negative value. I denotes how many ions the solute dissociates (or fragments) into. The solute potential decreases with the number of ions the solute can separate into.
Net solvent flow is always in the direction of solute concentration, moving from the side with the lower concentration to the side with the higher concentration. The solution to the left of the membrane, thus, has a greater negative water potential than the solution to the right of the membrane. Water will therefore pass through the membrane from the right side to the left. Water always gravitates toward a lower water potential.

During what stage does a cell 's nucleus divide to form two identical nuclei ?
Mitosis is the process through which a cell's nucleus divides into two new nuclei. During mitosis, one copy of the DNA is transferred to each of the two daughter cells.
Mitosis is a cell cycle step in which replicated chromosomes separate into two new nuclei. Mitosis produces genetically identical cells with the same number of chromosomes.
As a consequence, mitosis is also known as equational division. Mitosis is usually preceded by the S phase of interphase (during which DNA replication occurs) and is frequently followed by telophase and cytokinesis, which divides the cytoplasm, organelles, and cell membrane of one cell into two new cells with nearly equal proportions of these cellular components.
